Dynamic number insertion or DNI is a<\/span> call tracking<\/span><\/a> method that replaces a default website phone number with a tracking number according to defined visitor or traffic-source rules.<\/span><\/p>\n

For example, a visitor arriving from<\/span> Google Ads<\/span><\/a> may see a different number from someone arriving through organic search. In a more detailed setup, a number may be assigned to an individual visitor or session so a resulting call can be connected with available campaign and session data.<\/span><\/p>\n

When the visitor calls, the<\/span> tracking platform<\/span><\/a> forwards the call to the business while recording the attribution information associated with the tracking number.<\/span><\/p>\n

The result is a clearer connection between an inbound call and the marketing activity that preceded it. This guide explains how DNI works, the main tracking models, how number pools work, how to set up DNI, and how to fix common problems.<\/span><\/p>\n
